Recently actually!
Bono recently did say it was probably his favourite song, in a recent interview and not just from AB but over all.
His mind changes like the wind admitedly and this is probably why they have been playing it on this tour a bit.
The song to me has really great guitaring, especially live. It's definately one of my favourite moments from Dublin in June. The album version is very similar to the live version. I can say I got chills from it when I heard them sound checking it in Dublin.
I think personally the song probably means a hell of alot to Edge with his break-up at that time.
And the hate that Lillywhite refers to probably means they got sick of trying to mix it (ie:'it was the most typically U2-ish tracks that were proving the most difficult. "Who's Gonna Ride Your Wild Horses" (notably absent from the forthcoming Best of) as being especially testing)
